PROPOSAL <br />Civic Center 5tormwoterLiftStotionRenovation Design Services E # <br />hydrology and hydraulic modeling, planning, alternatives evaluation, and final design and cost <br />estimates for approximately 4.6 miles of street rehabilitation and storm drain facilities. <br />Dominguez Channel Watershed Study, Los Angeles County, California. Los Angeles <br />County Department of Public Works. Project Manager. Michael Baker is providing engineering <br />services to prepare a comprehensive flood hazard analysis for the Dominguez Channel <br />Watershed. Dominguez Watershed is approximately 75 -square miles and drains the southwest <br />portion of Los Angeles County. Dominguez Channel originates near the Los Angeles <br />International Airport (LAX) and extends to the Los Angeles Harbor running a length of <br />approximately 19.5 miles. The purpose of this study Is to evaluate the hydraulic capacity of the <br />existing levees along the channel and to identify deficiencies In Federal Emergency <br />Management Agency (FEMA) requirements. <br />Heritage Fields Drainage and Water Quality Master Plans, Irvine, California. Fivepoint <br />Communities (formerly Heritage Fields E/ Toro, LLC). Engineer responsible for hydrology <br />analysis to determine Impacts of the proposed development (850 acres) within the six regional <br />watersheds (Marshbum, Bee Canyon, Ague Chinon, Borrego, Serrano, and Upper San Diego <br />Creek). Tasks Included updating the land plan using Geographic Information System (GIS), <br />determining the stage -storage for Agua Chinon and Marshburn retarding Basin and performing <br />the rational and unit hydrographs with/without basins to meet Orange County criteria. Michael <br />Baker provided regional hydrology, master planning of backbone facilities, and GIS mapping for <br />the overall Heritage Fields project. The project encompasses 850 acres of the former EI Toro <br />Marine Corps Air Station and borders the Great Park. It will provide approximately 1,100 <br />residential dwelling units together with two golf courses, riparian corridors, lake features, and <br />trail connections. The master plan of drainage included six regional watersheds (Marshbum, <br />Bee Canyon, Ague Chinon, Borrego, Serrano, and Upper San Diego Creek) passing through <br />the project site and a master plan of water quality for all districts of Heritage Fields, <br />Master Plan of Storm Drainage for North and West Santa Ana River Tributary Areas, <br />Anaheim, California. City of Anaheim. Engineer responsible for hydrology analysis which <br />included watershed delineation and discharge for the hydraulic analysis. Storm Drain As -Built <br />drawings were obtained from the City of Anaheim and were analyzed with the new discharges <br />using WSPG. Storm drain systems were proposed if the existing system was inadequate. <br />Michael Baker was selected by the City of Anaheim to prepare an updated comprehensive <br />storm drainage master plan for the North and West Santa Ana River tributary areas. The new <br />plan was based on previous studies for the areas, updated to account for current hydrology <br />methods, new hydrology modeling in areas without existing studies, improvements to the storm <br />drain and tributary channel systems, and the latest land use planning. The new plan will model <br />existing storm drainage systems from as -built plans and identify deficiencies in the existing <br />street sections and storm drain systems based on the results of the hydrology and hydraulic <br />analyses. <br />14 T e I N 0 T 10 0 A L MUjahld Chandoo, P.E. <br />25B-50 <br />
